Abstract

One aspect provides a method of controlling an information flow in a data transmission system. In one embodiment, the method comprises receiving a plurality of data packets and generating a modified information flow. Data packets in the modified information flow are spaced with a variable spacing whilst the order of the data packets is maintained. The variable spacing between the data packets is exponentially distributed.
